TOBACCO-PIPE.

SPECIFICATION forming part of Letters Patent N 0. 675,768, dated June 4,1901.

Application filed April 23 1901.

To all whom it may concern:

Be it known that I, HENRY W. COMSTOCK, a citizen of the United States,residing at Boston, in the county of Suffolk and State of Massachusetts,have invented new and usefullmprovements in Tobacco-Pipes, of which thefollowing is a specification.

This invention relates to improvements in tobacco-pipes; and its objectis to prevent the distillation of nicotine and other deleterious oils,due, within the bowl of the pipe by, burning the tobacco from the bottomupward instead of from the top of the pipe downward.

The invention is carried out as follows, reference being had to theaccompanying drawings, wherein Figure 1 represents a side elevation ofthe improved tobacco-pipe. Fig. 2 represents a plan view of Fig. 1,showing the cover swung to one side of the bowl to permit the latter tobe charged or cleaned; Fig. 3 represents a central longitudinal sectionof the pipe, showing it in the position in which it is intended to beused; and Fig. 4 represents a detail plan View of the bowl-cover.

Similar letters refer to similar parts wher ever they occur on thedifferent parts of the drawings.

In the drawings, A represents the pi pebowl, having an internal cavity0., adapted to hold the tobacco.

B is the stem, leading from the lower end of the bowl and provided witha longitudinal perforation b, that is in communication with thebowl-cavity a ;by.-means of a conduit 0 in the bowl portion A, as shownin Fig. 3. The said channel or conduit 0 is arranged parallel, or nearlyso, to the bowlcavity a, as shown in said Fig. 3.

D is a cover pivotally arranged upon a screw E, that is screwed throughthe stem B about opposite to the perforation O, and said screw servesto,cover the perforation in the stem, through which the drill is passedin drilling the channel 0. In practice I make the outer end of saidscrew E in the form of a suitably-shaped knob or finger-piece e, adaptedto be held by the smoker while smoking.

To the under side of the cover D are se- Serial No. 57,067. (No model.)

cured a series of pins 01 d 02, adapted to rest against the open end ofthe bowl in such a manner as to leave a space F between the open end ofthe bowl and cover, so as to allow the air to enter the bowl during thesmoking operation, as shown in Figs. 1, 3, and 4.

In charging or cleaning the bowl the cover D may be swung to theposition shown in Fig. 2.

In pipes of ordinary construction, in which the mouth of the bowl isheld upward, the

tents, of the pipe as when the pipe is first lighted.

What I wish to secure by Letters Patent and claim is A. base-burningtobacco-pipe, consisting of a hollow bowl A, having a perforated stem B,communicating with the bowl at or near its open end, and having aconduit 0, con- -necting the stem and closed portion of the bowl, acover D, pivotally connected to a pin or screw E, c, said cover havingattached to its inner side a series of pins or projections d, d, d, forthe purpose of holding said cover from contact with the bowl so as topermit the air to pass through the space F, between the bowl and coversubstantially as herein described and shown, all being for the purposeof preventing the distillation of nicotine and other deleterious oilswithin the bowl of the pipe.

In testimony whereof I have hereunto set my hand in presence of twosubscribing witnesses.

HENRY W. COMSTOCK.
